    Areas affected...Portions of southwestern KS and northwestern OK

    Concerning...Severe Thunderstorm Watch 405...

    Valid 280147Z - 280315Z

    The severe weather threat for Severe Thunderstorm Watch 405
    continues.

    SUMMARY...A small, intense bowing complex will pose a threat for
    significant severe wind gusts of 75-100 mph this evening as it
    spreads eastward across southwestern Kansas and northwestern OK.

    DISCUSSION...Multiple measured severe wind gusts ranging from 65 mph
    up to around 100 mph and damage reports have recently occurred in
    the OK Panhandle with a small bowing cluster now moving into far
    northwestern OK and southwestern KS. Strong inbound velocities noted
    from KVNX around 9000 ft AGL along the apex of the bow suggest the
    development of a pronounced rear-inflow jet. The thermodynamic
    environment in the near term (next 1-2 hours) should remain quite
    favorable for significant severe wind gusts of 75-100 mph in a
    narrow corridor across far northwestern OK into southwestern and
    south-central KS. Instability gradually decreases with eastward
    extent into north-central OK and south-central KS along/north of a
    stalled surface boundary. The potential for significant severe winds
    farther east into these areas beyond 04Z (11 PM CDT) is less clear
    owing to the somewhat weaker instability. Still, some severe wind
    threat will likely persist tonight as the bowing complex develops
    eastward.
